worship gripe

An age old question that has plagued my mine since i was a teen whose brain and heart were open to worship, by GOd. What is it for. Whats the purpose? What is supposed to happen during worship? Are there rules? God doesnt seem to have many for us other than to pray, sing, dance, adore, and live in community with one another. Where the hell does the concept of a sermon even come into the picture? The Catholic Church has it right i think. THey read through scripture and then a breif HOmily is shared. I really cant stand that fact that an average worship service is one hour and we spend about half of that listening to one person talk at us about what He (typically) thinks God meant when he spoke or acted. With regards to a worship service. I think 90% of what we do in worship today is man made. Im thinking the Sunday morning one hour gathering is completely man made. Church is the people, worship is building of the kindgom. Fellowship is when the Kingdom builders gather to share, pray, encourage, meditate, become aware of the needs of the community and act upon them. So as far as church? Its any community of believers who agree to be in community as the Bible describes it in ACTS. What most denominations call worship is what they created to either appease or gather people. Oddly enough while Willow Creek overshadows the world with amazing programatic "worship services:, if you ask them, thier "worship services" are not worship services. They are celebrations. They would say that Church is occuring all over the region in houses, coffe shops, work places, etc. They share, learn, pray, become aware of one anothers needs and act upon them. they encourage one another in thier role of building the kingdom. So in a celebration, thier are no rules, just celebrate. As much as i though i hated Willow Creek over the years, i think they are actually doing it, well, as close to what Acts records. An who knows, maybe Acts isnt even what Jesus imagined for us in terms of worship. Dont get me started.
